Have 2004 Murano on the brink of 200,000 miles and have been seeing the white smoke from the tailpipe the last 3 or 4 starts. Have owned this car since new and not ready to part with it, curious if anyone can tell me approximate costs to have orings replaced? Thanks!
If you mean piston rings, that is an engine drop and teardown, as you would also do a general rebuild. Talk to local rebuilds but I would guess 3k or more.
If it's white smoke there is water getting into the combustion chamber. i.e. Cracked head,cracked block or head gasket or intake gasket. All are expensive repairs except intake gasket. Check for water in the oil.
